<p>A system (50) controls the laser-induced discharging of pixel-sized image areas on a photoreceptor (18) in a multi-color xerographic printer where multiple layers of toner are placed on the photoreceptor surface. A light collector (40), disposed to collect light either reflected (12a) from or passing through the photoreceptor, detects conditions in which the laser beam (12) must pass through one or more layers of previously-placed toner to discharge the photoreceptor. When such a condition is detected, the system (50) increases either the intensity or exposure duration of the laser beam (12). <IMAGE></p> |
